Controlled environment secure media streaming system

ABSTRACT

A Controlled Environment Secure Media Streaming System with Digital Video Recording (DVR) manages the delivery of content to Secured Devices. Cloud Services provide content to Integration Hub. The Integration Hub interfaces with various cloud services providers and prepares content for consumption by a resident of a secured facility. Integration Hub utilizes Content Filter to inspect content received from cloud service providers for suitability for use in a secured environment. Once content is retrieved, filtered, formatted, and packaged by Integration Hub, the content is stored in Data Warehouse. When requested content is not available, the system schedule a future retrieval or DVR of the content when it becomes available. When the system detects that the content is stopped, the system creates a bookmark, so the user can resume the content at the bookmarked portion at a later time.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of U.S. patent application Ser. No. 16/737,053 filed on Jan. 8, 2020, which is a continuation application of U.S. patent application Ser. No. 15/663,507 filed on Jul. 28, 2017 titled CONTROLLED ENVIRONMENT SECURE MEDIA STREAMING SYSTEM WITH DIGITAL VIDEO RECORDING, which are incorporated herein by reference in their entireties and are considered to be part of this specification.

BACKGROUND Field

The disclosure relates to methods and systems for delivery of schedule and/or recorded content from cloud service providers in secured facilities.

Background

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort. One subset of cloud computing includes the delivery of services such as multimedia and other content. Cloud services are now ubiquitous parts of the modern mobile computing environment. Examples of cloud services are music delivery, video delivery, streaming music, streaming video, digital books, digital magazines, games, or other software applications. Some examples of well-known cloud services are Spotify™ and Pandora™ for music, Netflix™ and Hulu™ for video and movies, and the App Store™ or Google Play™ for applications (“apps”) and games for mobile devices.

BRIEF SUMMARY

In an embodiment, a Controlled Environment Secure Media Streaming System with Digital Video Recording (DVR) manages the delivery of content to a number of Secured Devices. Cloud Services are any type of centrally-distributed service that are delivered to a computing device. For example, Cloud Services 102 can be music delivery, video delivery, streaming radio, streaming video, digital books, digital magazines, games, or other software applications (“apps”). Some cloud services are third party products or services. Each Cloud Service delivers or makes available some kind of content. Examples of the content delivered by Cloud Services are music, video, radio, movies, television shows, digital books, digital magazines, games, or applications (“apps”).

Numerous third party cloud services exist and the cloud services delivery system is adaptable to be compatible with any third cloud services provider. Some cloud services deliver content one time, for example an application need only be downloaded one time and may be used locally many times. Some cloud services make available vast libraries of content that are streamed on demand by the end user. The Controlled Environment Secure Media Streaming System with Digital Video Recording is compatible with one-time delivery of content, on-demand streaming of content, and access to libraries of content.

A unit of content is whatever is the appropriate measure of content for each cloud service. For example, a unit of content for a music provider is either a song, an album, or a collection of songs or albums. The unit of content for a video provider is one film, episode, series of episodes, video clip, or a collection of films, episodes, series of episodes, and/or video clips. In an embodiment, the unit of content may be a single viewing or accessing of a film, video, song, or album. In such an embodiment, viewing or accessing the content a second time would be counted as a second unit of content. The user may be interrupted while viewing or accessing the content. In such instances, it would be helpful to have the ability to pause the video or content and allow the user to resume viewing the video at substantially the same spot/portion at a later time. In an embodiment, the system detects that the user is no longer viewing the video or content. In such embodiments, the system automatically bookmarks the portion of the video, song, album, clip, etc., when the user stopped viewing the video, so the user can resume viewing/listening to the content at substantially the same portion of the video, song, album, clip, etc. at a later time.

In some embodiments, the unit of content is time limited access to a library of content. For example, a music provider may sell a month of access to a library of music for a flat fee. During this period of time the end user has unlimited access to the entire library of content. Other timeframes may be available as well, such as daily or weekly access to libraries of content. Other units of content are within the scope of the Controlled Environment Secure Media Streaming System as well, as determined by the requirements and availability set by Cloud Service Providers.

In an additional embodiment, the unit of content is access to a future song or video that is not yet available to the public. For example, the unit of content includes a song, movie, episode, series of episodes, or video clip that has not yet been released/broadcast to the public. In such an embodiment, a user may schedule, or configure, the digital video recording system to record, or otherwise store, the future broadcast/release of the desired content. For example, the user may configure the digital video recording system to record content as it is broadcast on live television.

Cloud Services provide or make available content to an Integration Hub. The

Integration Hub interfaces with various cloud services providers and prepares content for consumption by a resident of a secured facility. Integration Hub utilizes a Content Filter to inspect content received from cloud service providers for suitability for use in a secured environment. Only permitted content is allowed to enter the Controlled Environment Secure Media Streaming System. Once content is retrieved, filtered, formatted, and packaged by Integration Hub, the content is stored in Data Warehouse. Data Warehouse may be any type of data storage and retrieval system suitable to store and retrieve disparate types of data and content.

The Distribution Hub manages connections to a plurality of Secured Devices. Secured Devices request content from the Distribution Hub, the Distribution Hub retrieves the content from the Data Warehouse, and then Distribution Hub manages the transfer of content to the Secured Devices. In some embodiments, Distribution Hub utilizes the Content Filter to determine whether or not a particular Secured Device can access particular content. More specifically, the Distribution Hub maintains, or has access to, account information for each Secured Device and/or the owner of the Secured Device. When content is requested by the Secured Device, the Distribution Hub determines whether the content can be transferred to the Secured Device(s) based on the respective Secured Device(s) account(s) and/or the owner(s) of the Secured Device(s) account(s).

The Distribution Hub records content distribution and access by Secured Devices and reports usage to the Reporting Services Module. Reporting Services Module, in turn, aggregates usage information and reports back to the respective Cloud Services.

The foregoing and other aspects, features, details, utilities, and advantages will be apparent from reading the following description and claims, and from reviewing the accompanying drawings.

Environment Overview

The Controlled Environment Secure Media Streaming System with Digital Video Recording is designed to operate within a controlled environment. In an embodiment, the controlled environment is a correctional institution such as a prison facility and the residents are inmates or otherwise incarcerated in the correctional institution. In other embodiments, the controlled environment may be any type of facility with a need to control and monitor content consumption such as a hospital, a dormitory, a mental health institution, a hotel, or other such facilities. These types of controlled environments have unique requirements regarding the distribution and consumption of content and media that are not present in other, non-controlled environments. For example, in a prison, the authority operating the prison has a strong interest in controlling the consumption and exposure to media and other content. For example, extremely violent media and content is not appropriate for a violent offender. In another example, some media content is associated with particular social movements or gang activity and may be deemed not appropriate for prisoner consumption. Even in the case of appropriate content, prison authorities may control access to media and content, for example as a reward for good behavior. In these ways, conventional media and content distribution systems do not address the unique needs and requirements of a system designed for controlled environments.

FIG. 1A illustrates an embodiment of a Controlled Environment Secure Media Streaming System 100A. Cloud Services 102 are any type of centrally-located and/or internet distributed service that may be transmitted or delivered to a personal computing device. For example, Cloud Services 102 can be music delivery, video delivery, streaming radio, streaming video, digital books, digital magazines, games, or other software applications (“apps”). Some cloud services are third party products or services. Each Cloud Service delivers some kind of content. Examples of the content delivered by Cloud Services 102 are music, video, radio, movies, television shows, digital books, digital magazines, games, or apps.

Numerous third party cloud services exist and the cloud services delivery system is adaptable to be compatible with any third cloud services provider. Some cloud services deliver content one time, for example an application need only be downloaded one time and may be used many times. Some cloud services make available vast libraries of content that are streamed on demand by the end user. The cloud services delivery system is compatible with one-time delivery of content, on-demand streaming of content, and access to libraries of content. In an embodiment, the cloud services include institutional content. For example, in an embodiment, the content includes job-specific training to be performed at a specific correctional facility. In another embodiment, the institutional content may be a presentation and/or training created by the institution to teach life skills such as job interview skills, networking, time management, etc.

A unit of content is whatever is the appropriate measure of content for each cloud service. For example, a unit of content for a music provider is either a song or an album. The unit of content for a video provider is one film, episode, series of episodes, or video. In some embodiments, the unit of content may be a single viewing or accessing of a film, video, song, or album. In some embodiments, the unit of content is time limited access to a library of content. For example, a music provider may sell a month of access to a library of music for a flat fee. Other timeframes may be available as well, such as daily or weekly access to libraries of content. Other units of content are within the scope of the Controlled Environment Secure Media Streaming System 100 as well, as determined by the requirements and availability set by Cloud Service Providers 102.

Cloud Services 102 provide content to Integration Hub 104. The Integration Hub 104 interfaces with the various cloud services providers and prepares content for consumption by a resident of a secured facility. Integration Hub 104 utilizes Content Filter 120 to inspect content received from cloud service providers for suitability for use in a secured environment. Only permitted content is allowed to enter the Controlled Environment Secure Media Streaming System. Once content is retrieved, filtered, formatted, and packaged by Integration Hub 104, the content is stored in Data Warehouse 106. Data Warehouse 106 may be any type of data storage and retrieval system suitable to store and retrieve disparate types of data and content.

Distribution Hub 108 manages connections to a plurality of Secured Devices 110-116. Secured Devices request content from the Distribution Hub 108, the Distribution Hub 108 retrieves the content from the Data Warehouse 106, and then Distribution Hub 108 manages the transfer of content to the Secured Devices. In some embodiments, Distribution Hub 108 utilizes Content Filter 120 to determine whether or not a particular Secured Device can access particular content. More specifically, the Distribution Hub maintains, or has access to, account information for each Secured Device and/or the owner of the Secured

Device. When content is requested by the Secured Device, the Distribution Hub determines whether the content can be transferred to the Secured Device(s) based on the respective Secured Device(s) account(s) and/or the owner(s) of the Secured Device(s) account(s).

Distribution Hub 108 records content distribution and access by Secured Devices 110-116 and reports usage to the Reporting Services Module 118. Reporting Services Module 118, in turn, aggregates usage information and reports back to the respective Cloud Services 102.

In an embodiment, Controlled Environment Secure Media Streaming System further comprises at least one profile database (not shown). In such embodiments, the profile database is configured to store a plurality of profiles, one profile for each user/inmate. The profile database stores information such as the user/inmate's personal information, access restrictions, purchase history, browsing history, streaming history, account information, payment information, scheduled recordings, subscriptions, and/or bookmarks indicating the last portion of a video, song, etc. the user viewed/heard before pausing the content.

The profile database may reside within Integration Hub 104, Data Warehouse 106, Distribution Hub 108, a Secured Device, and/or the profile database may reside at a location remote from each of the foregoing entities. The profile database is implemented using any commercially available database management system such as Microsoft Access, Microsoft SQL server, an Oracle database, an IBM database, etc. The profile database maintains communicative connections via traditional networking infrastructure such as routers, switches, hubs, firewalls, etc.

The user may be interrupted while viewing or accessing the content. In an embodiment, Distribution Hub 108 is configured to pause the video or content, update the user's profile and/or streaming history, and allow the user to resume viewing the video at substantially the same spot/portion at a later time. In an embodiment, Distribution Hub 108 and/or Secured Device 110 detects that the user is no longer viewing the video or content. In such embodiments, the system automatically bookmarks the portion of the video, song, album, clip, etc. when the user stopped viewing the video and updates the user's profile and/or streaming history with the bookmark information, so when the user resumes the content, the content resumes at substantially the same portion of the video, song, album, clip, etc.

In an embodiment illustrated in FIG. 1B, the Content Filter 120 is integral to either the

Integration Hub 104 or the Distribution Hub 108, or duplicated in both. In these embodiments, the Content Filter 120 is either shared between the Integration Hub 104 and the Distribution Hub 108 or both the Integration Hub 104 has a Content Filter and the Distribution Hub 108 has a second Content Filter.

In an embodiment illustrated in FIG. 1C, the Data Warehouse 106 is omitted for streaming content. For example, there is no need to store data in the Data Warehouse 106 for content that is streamed in real-time from Cloud Services 102. In these embodiments, the content is still formatted, packaged, and processed by the Integration hub 104.

Integration Hub

FIG. 2 illustrates an embodiment of Integration Hub 104. The Integration Hub 104 interfaces with various cloud services providers and prepares content for consumption by a resident of a secured facility. The Integration Hub 104 can interface with cloud services providers in a number of ways. Some cloud services provide an application programming interface (API) to interface with their service. In these cases the Integration Hub 104 utilizes the cloud provider's API to retrieve content from the cloud service provider. Some cloud services providers may not have an API but make available an endpoint through which clients can request content. For these types of cloud services the Integration Hub 104 provides for a connection to the data endpoint for content retrieval. The Integration Hub 104 is a modular design so that any number of Cloud Services 102 may be supported by the Integration Hub 104. Each Cloud Service provider has its own module 202-206 in the Integration Hub 104 to manage the connection to that Cloud Service provider. After retrieving content from cloud service providers, the Integration Hub 104 screens, formats, and packages the content for consumption.

Data Formatter 210 converts received content to formats compatible with Secured Devices 110-116. To this end, the Data Formatter 210 is configured with a plurality of conversion algorithms for converting certain incompatible formats to other compatible formats. The various conversion algorithms may be implemented in software and/or hardware. This allows the Controlled Environment Secure Media Streaming System 100 to be compatible with a wide range of content sources while at the same time not requiring each Secured Device 110-116 to be compatible with a large number of formats. For example, in an embodiment, Secured Device 110 is only capable of playing music encoded in the MP3 format and a certain cloud service provider only makes music available in the AAC format. In this example, the Data Formatter 210 re-encodes the AAC files from the cloud service provider into MP3 format files suitable for the Secured Device. The same type of transcoding is applicable to encoded content types such as video and audio. Other content types also have data formatting issues too. For example, electronic books are made available in various formats such as ePUB, Mobi, or PDF. Games and apps are also packaged in particular file format, for example the Android Application Package (APK) used by the Android™ operating system. The Data Formatter 210 is capable of converting or transcoding any necessary format, encoding, or file type as necessary to provide compatibility with a wide range of cloud service providers.

In some embodiments, cloud service providers require Digital Rights Management (DRM) of their content. DRM refers to various access control technologies that are used to restrict the usage of content. Controlled Environment Secure Media Streaming System 100 is compatible with a range of DRM systems that are well known to those of skill in the art. In these embodiments, the cloud service provider may either supply their own DRM scheme or require the Controlled Environment Secure Media Streaming System 100 to add its own DRM layer to content. In either case, the Data Packager 212 manages DRM for content to be delivered to Secured Devices 110-116. The Data Packager 212 ensures that any DRM that passes through the Integration Hub 104 is compatible with the Secured Devices 110-116.

In an embodiment, Integration Hub 104 further comprises at least one profile database (not shown). In such embodiments, the profile database is configured to store a plurality of profiles, one profile for each user/inmate. The profile database stores information such as the user/inmate's browsing history, streaming history, scheduled recordings, subscriptions, and/or bookmarks indicating the last portion of a movie, song, show, etc. that the user viewed/heard before pausing the content.

In an additional embodiment, Integration Hub 104 further comprises at least one future content database (not shown). In such embodiment, the future content database is configured to store data describing content to be recorded, or otherwise retrieved, from Cloud Services 102 at a future time.

Content Filter

Content Filter 120 inspects content data received from cloud service providers for suitability for use in a secured environment. In an embodiment, the Content Filter 120 analyzes a unit of content and returns a binary value indicating whether or not the unit of content should be filtered. In an embodiment, the Content Filter 120 scans incoming content and application data for viruses or malware. In an embodiment the Data Formatter 210 screens content for censorship. For example, content related to breaking out of prison would be inappropriate for a prisoner to receive. Similarly, the operating authority of any secured facility may enact certain content filters for suitability in their environment. In another example, a juvenile facility can block movies with an MPAA rating unsuitable for minor consumption. These are just some examples of the censorship the Content Filter 120 is capable of.

In an embodiment, Content Filter 120 operates on cloud provider supplied meta-data, such as industry standard ratings for music, movies, and games. Provider supplied meta-data would include industry standard ratings such as MPAA ratings. In other embodiments, Content Filter 120 analyses the content to filter out some content. For example, in an embodiment Content Filter 120 maintains a keyword block list that can operate on any kind of media. The keyword block list can contain words, phrases of multiple words, or portions of words. Content Filter 120 applies the keyword block list to text-based content by running a search for elements in the block list. For example, a book may be filtered based on censorship if it contains a word or phrase in the block list. Content not based on text data such as books can also be censored using the block list. Audio content is processed through a speaker independent voice recognition system to produce searchable text on which the block list can operate. Video content also containing audio can similarly be processed using speaker independent voice recognition to produce searchable text. Alternatively, some video content has close captioning content embedded in it that can be the basis for the block list text search. Likewise, video processing algorithms can be utilized for detecting video content that is unacceptable, such as scenes containing graphic violence or nudity, among other things.

Data Warehouse

After various data and content are retrieved, formatted, and packaged by the Integration Hub 104, the Cloud Services Delivery System stores data and content in a Data Warehouse 106. Data Warehouse 106 may be any type of data storage and retrieval system suitable to store and retrieve disparate types of data and content. In an embodiment, Data Warehouse 106 employs data de-duplication technologies to reduce the storage needs of large amounts of content. In an embodiment, Data Warehouse 106 is centralized and shared among many secured facilities. In another embodiment, Data Warehouse 106 is located on site at the secured facility and provides for local access to the content stored in the Data Warehouse 106. Data Warehouse 106 may also be implemented in a hybrid fashion, such that there is one centralized location storing all content, and various endpoint caches located at or near secured facilities with Cloud Services Delivery systems to offload some of the storage and retrieval requirements from the centralized Data Warehouse 106. In this way, Data Warehouse 106 acts as a content delivery network or CDN.

In an embodiment, Data Warehouse 106 is configured to record, or otherwise retrieve and store, a future broadcast/release of the scheduled content. For example, when a television show is requested based on an user/inmate's subscription, Data Warehouse 106 records the content as it is broadcast on live television and/or otherwise retrieves the content as it becomes publicly available through a Cloud Service.

In an embodiment, Data Warehouse 106 is implemented on server and storage hardware, and in another embodiment, Data Warehouse 106 is implemented as a software layer on top of a third party data storage and retrieval system.

In an embodiment, Data Warehouse 106 is bypassed for streaming or on-demand content. Data Warehouse 106 can still provide CDN capabilities to on-demand or streaming content even if the content is not stored for long periods of time. In another embodiment, Data Warehouse 106 is bypassed entirely for streaming and other on-demand content such that content is delivered directly from the Integration Hub 104 to the Distribution Hub 108. In either embodiment, streaming content may be buffered at the Distribution Hub 108 or the Data Warehouse 106 as appropriate. For example, when a user operating a Secured Device pauses the playback of streaming or on-demand content the stream may be buffered at either location. In addition, streaming content may not be buffered at all and merely cease streaming while the content playback is paused.

In an embodiment, Data Warehouse 106 further comprises at least one profile database (not shown). In such embodiments, the profile database is configured to store a plurality of profiles, one profile for each user/inmate. The profile database stores information such as the user/inmate's browsing history, streaming history, scheduled recordings, subscriptions, and/or bookmarks indicating the last portion of a movie, song, show, etc. that the user viewed/heard before pausing the content. When the user/inmate resumes the content, the content resumes at substantially the same portion of the video, song, album, clip, etc.

Distribution Hub

FIG. 3 illustrates one embodiment of the Distribution Hub 108. Distribution Hub 108 manages the distribution of content to Secured Devices 110-116. Distribution Hub 108 receives content requests from a Secured Device, retrieves the content from the Data Warehouse 106, and delivers it to the Secured Device. If the requested content is not available in the Data Warehouse 106, Distribution Hub 108 makes a request to the Integration hub 104 to retrieve the data from the appropriate Cloud Service 102.

Distribution Hub 108 employs access restrictions by Access Restriction Manager 304 on content to be delivered to Secured Devices. In an embodiment, Access Restriction Manager 304 includes all of the capabilities of Content Filter 120, but are applied on a per-resident basis rather than system-wide. For example, the Content Filter 120 may allow a particular music album to be added to the Data Warehouse 106 for a facility. However, restrictions from the Access Restriction Manager 304 can be enacted on a per-resident basis in the Distribution Hub 108 to prevent a particular resident to access that particular music album. In some embodiments, Access Restriction Manager 304 does not perform censorship and all censorship is performed by Content Filter 120. In some embodiments, Content Filter 120 is omitted and all censorship is performed by Access Restriction Manager 304. Other embodiments have censorship performed by both Content Filter 120 and Access Restriction Manager 304. The purpose of having two stages of censorship is to apply differing levels of censorship at the secured facility level and at the individual level. To provide an example, there may be certain types of content restricted from general distribution to any inmates, whereas each individual inmate may have personal restrictions that further specifically limit the types of content they are permitted to access.

In an embodiment, Content Filter 120 is directly used by Access Restriction Manager 304 to power the content filtering and censorship role of the Distribution Hub 108. In this embodiment the Access Restriction Manager 304 is essentially a gateway to the Content Filter 120 and the Access Restriction Manager 304 does not include censorship logic of its own. This reduces the complexity of the Distribution Hub 108. In an embodiment, the Content Filter 120 is external to Integration Hub 104. In other embodiments, the Content Filter 120 is integral to Integration Hub 104, but made available to the Distribution Hub 108. In another embodiment, Distribution Hub 108 contains its own content filtering and censorship engine separate from the Content Filter 120 of the Integration Hub 104.

In an embodiment, the Access Restriction Manager 304 of the Distribution Hub 108 screens for content censorship. For example, book content on breaking out of prison would be inappropriate for a prisoner to receive. Similarly, the operating authority of any secured facility may enact certain content filters for suitability in their environment. In another example, a juvenile facility can block movies with an MPAA rating unsuitable for minor consumption. These are just some examples of what kind of censorship the access restrictions of the Access Restriction Manager 304 is capable of. In some embodiments the access restrictions of the Access Restriction Manager 304 operates on cloud provider supplied meta-data, such as industry standard ratings for music, movies, and games. In some embodiments, the access restrictions of the Access Restriction Manager 304 analyses the content directly to filter out some content. For example, in an embodiment the access restrictions of the Access Restriction Manager 304 maintains a keyword block list that can operate on any kind of media. The keyword block list can contain words, phrases of multiple words, or portions of words. Access Restriction Manager 304 applies the keyword block list to text-based content by running a search for elements in the block list. For example, a book may be filtered based on censorship if it contains a word or phrase in the block list. Content not based on text data such as books can also be censored using the block list. Audio content is processed through a speaker independent voice recognition system to produce searchable text on which the block list can operate. Video content also containing audio can similarly be processed using speaker independent voice recognition to produce searchable text. Alternatively, some video content has close captioning content embedded in it that can be the basis for the block list text search.

In an embodiment, Access Restriction Manager 304 further enforces usage restrictions on Secured Devices 110-116. Usage restrictions operate in addition to content filtering or censorship. For example, the Access Restriction Manager 304 can restrict usage to a particular time of day, day of week, or location within the secured facility. In one embodiment this usage restriction only applies to acquisition of new content. For example, the Distribution Hub 108 may only allow new content to be transferred to the Secured Device during certain hours in the day. In this embodiment the Secured Device 110 can access content that is stored locally on the Secured Device 110 outside of these restricted times. In another embodiment, the Secured Device 110 requires authorization to access content stored on the Secured Device 110. This authorization comes from the Access Restriction Manager 304. In these embodiments, access to content can be restricted to certain hours of the day, or location. For example, in one embodiment the Access Restriction Manager 304 only allows access to content in a common area, and does not allow the Secured Device 110 to access content when the Secured Device 110 is in a prisoner's cell. In this way, access control to content, whether it is stored in the Data Warehouse 106 or on the Secured Device 110 is centrally controllable by the Distribution Hub 108 through the Access Restriction Manager 304.

The Distribution Hub 108 manages connections to Secured Devices 110-116 through the Connection Manager 306. In an embodiment, the Connection Manager 306 transfers content to Secured Devices 110-116 over a wireless network. Examples of wireless networks include Wi-Fi, cellular, Bluetooth, ZigBee, WiMAX, or other suitable wireless communications medium. In an embodiment, the Connection Manager 306 transfers content to Secured Devices 110-116 over a wired network. The wired network can either be always-connected or periodically connected. For example, in an embodiment the Distribution Hub 108 is integral to a stationary kiosk. The stationary kiosk has a data connection port compatible with a Secured Device. The data connection port may be, for example, an Ethernet port or a USB port. When a Secured Device is connected to the data connection port of the stationary kiosk, the Secured Device synchronizes with the Distribution Hub 108 to receive new content from Cloud Services 102. When the Secured Device is disconnected from the stationary kiosk, it can no longer receive content from the Distribution Hub 108. In other embodiments, the wired or wireless connection from the Distribution Hub 108 to the Secured Device is always on. In these embodiments the Secured Device can access content from Could Service 102 at any time.

In an embodiment, Distribution Hub 106 further comprises at least one profile database (not shown). In such embodiments, the profile database is configured to store a plurality of profiles, one profile for each user/inmate. In an embodiment, Data Warehouse 106 further comprises at least one profile database (not shown). In such embodiments, the profile database is configured to store a plurality of profiles, one profile for each user/inmate. The profile database stores information such as the user/inmate's browsing history, streaming history, scheduled recordings, subscriptions, and/or bookmarks indicating the last portion of a movie, song, show, training, etc. using the techniques described above.

Secured Device

Secured Devices 110-116 facilitate content consumption. In an embodiment, Secured Device 110 is a tablet computer. In another embodiment, Secured Device 110 is a stationary kiosk. In all embodiments, Secured Devices 110-116 comprise hardware and/or software that enable residents of secured facilities to consume or experience content from cloud service providers. For example, in an embodiment Secured Device 110 is a tablet computer that includes at least one user interface capable of playing/displaying video and audio files from various Cloud Service Providers 102. The user interfaces of Secured Device 110 includes at least a screen for consuming visual content and speakers or a headphone output for playing audio content. In some embodiments, Secured Device 110 does not have speakers but does have a headphone output.

In an embodiment, Secured Device 110 is a personal computing that is unique to a particular user. The personal computing device requires the user to authenticate prior to accessing Cloud Services 102. The Secured Device 110 is compatible with a range of authentication mechanisms, including passwords and biometrics. In an embodiment, the biometrics used include one or a combination of fingerprints, 3D images, 2D images, voiceprints, signatures, or the like. 3D and 2D images of facial features can be used in combination with facial recognition to authenticate users.

In an embodiment, Secured Device 110 is a kiosk comprising hardware and software to enable distribution of content to other content consumption devices. A user can bring a player device to the kiosk and transfer content from the kiosk to the player device. The user can then return to their living area to consume content acquired from the kiosk.

In some embodiments, Secured Device 110 also contains hardware and/or software to support other forms of communication. For example, in an embodiment, Secured Device 110 supports bi-directional voice and video calling. In an embodiment, Secured Device 110 also supports email and other text based communications such as SMS messaging. In this way, a single Secured Device 110 supports not only content consumption through the Controlled Environment Secure Media Streaming System 100 but also other forms of communication and entertainment.

Reporting Services

Many cloud service providers require reporting of usage information for purposes including but not limited to royalty payment calculation and license payment calculation. For example, if a cloud service provider provides music to the Controlled Environment Secure Media Streaming System 100 for playing in secured facilities, the Controlled Environment Secure Media Streaming System 100 needs to report back to the provider the number of times the music is played for the purposes of calculating the royalty rate that needs to be paid to the cloud service provider. Because the cloud service provider only sends a single copy of the music to the Controlled Environment Secure Media Streaming System 100, it does not have information on how many individual Secured Devices have received and/or played the music.

When the Distribution Hub 108 delivers a unit of content to a Secured Device, it sends a report to Reporting Services 118 indicating a delivery of the content. In some embodiments, content is licensed for unlimited plays once purchased. In these embodiments a single delivery report is generated the first time the content is delivered to a Secured Device. In some embodiments, content is licensed by consumption. For example, a movie may require a royalty payment for each time the movie is played. This is analogous to a movie rental. In these cases, the content is delivered by the Distribution Hub 108 to the Secured Device 110 with a Digital Rights Management (DRM) layer. Such DRM systems are well known to those skilled in the art. A unit of content with a DRM layer requires authorization for each time the content is accessed. In these embodiments, the Distribution Hub 108 sends a signal to Reporting Services 118 each time the DRM encapsulated content is accessed on the Secured Device 110.

Reporting Services 118 accumulates all of the content access information for each cloud service. Some access information relates to delivery of content, for example the download of a single song. Some access information related to the accessing of that content, for example each time the song is played on the Secured Device. The Reporting Services 118 aggregate both kinds of usage information as necessary for each Cloud Service 102.

In an embodiment, usage information is transmitted to the Cloud Service 102 as soon as it is received by the Reporting Services 118. In another embodiment, usage information is collected over a period of time and transmitted to the respective Cloud Service 102 once for a period of time. For example, some Cloud Services 102 may require monthly reporting of usage information.

In addition to the usage information, Reporting Services 118 can calculate the royalty payment to be paid to a particular Cloud Service 102. The Royalty can be based on content delivery or content access. Also, Reporting Services 118 can report information not related directly to a royalty, such as information useful for market research or demographic information.

Payment Options

Access to content from Cloud Services 102 can be paid for in a number of ways. In an embodiment, payment is processed by a Payment Processor 302 component of the Distribution Hub 108. In an embodiment, the Payment Processor 302 is separate from the Distribution Hub 108. In an embodiment, the Payment Processor 302 is a shared resource with other systems that also use the Payment Processor 302. For example, one other system that could use the Payment Processor 302 is an inbound and/or outbound voice and video communication system.

In an embodiment, residents of the secured facility set up a Debit Account to pay for access to content from Cloud Services 102. The Debit Account can be stored in one or more databases inside or out of the Controlled Environment Secure Media Streaming System 100. For example, the Debit Account can be stored and managed in Controlled Environment Secure Media Streaming System 100 within the system, or can located and accessed remotely, such as at a financial institution. The resident can load funds onto the Debit Account in person, for example at a commissary, by electronic means, or by telephone. Funds can be added to the Debit Account from cash, bank accounts, or credit card accounts. Optionally, non-residents of the secured facility can be allowed to add funds to the resident's Debit Account as well.

As another form of payment, an Advance Pay Account can also be associated with the resident. The Advance Pay Account can be funded by family and friends, and used for call fees associated with the resident. As with the Debit Account, the Controlled Environment Secure Media Streaming System 100 can access the Advance Pay Account to determine that there are sufficient funds, when content is purchased. In an embodiment, the Advance Pay Account is stored in one of the databases. In an embodiment, the Advance Pay Account can support any type of cloud service content.

In an embodiment, the Payment Processor does not immediately deduct funds from an account, but accumulates usage over a billing cycle and forwards a bill to the resident at the end of the billing cycle. Parameters such as the length of the billing cycle, the total amount allowed to be billed during one billing cycle, and the forms of payment that the bill can be paid in can be adjusted to suit the needs of a particular secured facility.

Operation

Operation of an exemplary Integration Hub 108 is illustrated in FIG. 4, which illustrates a method 400 for delivery of content from cloud service providers in secured facilities. At step 402, a request is received from the Distribution Hub 108 for a unit of content. The request is formatted and sent to the appropriate Cloud Service in step 404. In response, the Integration Hub 104 receives the requested content from the Cloud Service in step 406. At step 407 the Content Filter 120 is utilized to filter out content not suitable for the secured facility environment. If the unit of content is not suitable for the secured facility, the method ends at step 414. If the unit of content is suitable for consumption in the secured facility, the content is analyzed and transcoded in to an appropriate format by Data Formatter 210 in step 408 if necessary. The Integration Hub 104 maintains a list of acceptable formats supported by the Secured Devices. If the received content is not formatted in one of the appropriate formats, the content is transcoded into an appropriate format. If the content is received from the Cloud Service in an appropriate format that the Secured Devices can consume, no formatting or transcoding may be necessary.

At step 410 the content is packaged for consumption by Data Packager 212. In some embodiments, cloud service providers require Digital Rights Management (DRM) of their content. DRM refers to various access control technologies that are used to restrict the usage of content. Controlled Environment Secure Media Streaming System 100 is compatible with a range of DRM systems that are well known to those of skill in the art. In these embodiments, the cloud service provider may either supply their own DRM scheme or require the Controlled Environment Secure Media Streaming System 100 to add its own DRM layer to content. In either case, the Data Packager 212 manages adding DRM for content to be delivered to Secured Devices 110-116. The Data Packager 212 ensures that any DRM that passes through the Integration Hub 104 is compatible with the Secured Devices 110-116.

Finally, in step 412 the formatted and packaged content is delivered to the Data Warehouse 106 for storage. Once in the Data Warehouse 106, the Distribution Hub 108 is able to retrieve the content from the Data Warehouse and will not need to request the same content again from the Integration Hub 104. Data Warehouse 106 stores the formatted and packaged unit of content for a configurable length of time. Several algorithms may be used to determine when a particular unit of content is deleted from the Data Warehouse 106. In one embodiment, Data Warehouse 106 uses a least recently used algorithm to determine when to expunge content to make room for newly processed content. In another embodiment, Data Warehouse 106 uses analysis of frequency of use to determine which content to expunge. In any embodiment, the Data Warehouse 106 makes a best effort to maintain as much processed and packaged content as possible that is ready for instant delivery to consumers in order to avoid potential delays due to processing by the Integration Hub 104.

Operation of an exemplary Distribution Hub 108 is illustrated in FIG. 5. First, in step 502, a request for a unit of content is received from a Secured Device. The request indicates the unit of content requested on the Secured Device, for example a particular song or video. At step 504, the Distribution Hub 108 makes a preliminary check of access restrictions by using Access Restriction Manager 304. At this stage, Access Restriction Manager 304 can make an initial decision of whether the content requested is allowed to be delivered to the requestor based on available information. Information available at this step include identifying information about the content, including the content type, the title or other identifying name, the requesting device and user, and the time of request. The Access Restriction Manager 304 can filter out the content request without actually requesting the content, so that the Distribution Hub 108 does not need to request the content from the Integration Hub 104 if the content is not required to make the filtering decision. For example, if the requester does not have authorization to consume content at the time and place of requesting, then the Distribution Hub 108 can stop processing at this preliminary step. In another example, the unit of content may be blocked due to an inappropriate rating or subject matter for the entire secured facility. By making these determinations early in the process, the system can avoid unnecessary processing and network load.

At step 506 the Distribution Hub 108 requests the content from the Data Warehouse 106. If the Data Warehouse 106 does not have the requested content, at step 508 the Distribution Hub 108 makes a request to the Integration Hub 104 to acquire the content from an appropriate Cloud Service. The Distribution Hub 108 waits an amount of time, then checks the Data Warehouse 106 again to determine if the content has been added to the Data Warehouse 106. In an alternative embodiment, Distribution Hub 108 listens for a signal from the Data Warehouse 106 or the Integration Hub 104 that indicates the unit of content is ready for distribution. Once the content is present in the Data Warehouse 106, at step 510 the Distribution Hub 108 receives the content from the Data Warehouse 106.

At optional step 509, and as further illustrated in FIG. 6, when the content is not available at an appropriate Cloud Service, Integration Hub 104 is configured to schedule a future retrieval of the content when it becomes available. In such an embodiment, step 509 further includes scheduling a digital video recording of the content as it becomes available.

At step 512, the Access Restriction Manager 304 determines whether the requested content can be provided to the requesting Secured Device and user. At this step, the Access Restriction Manager 304 has more information available with which to make a final determination. Specifically, the Access Restriction Manager 304 now has full access to the content and can make censorship decisions based on the entirety of the content. At this step the keyword filtering and meta-data based filtering can result in the content access being denied even though the content passed the initial filtering step at step 504. In an embodiment, Access Restriction Manager 304 caches censorship decisions so that the content does not need to be re-analyzed for every access restriction determination. Access Restriction Manager 304 also re-analyses time-based restrictions at step 512 as significant time may have elapsed in the acquisition process between step 504 and step 512. These time based restrictions include any time-of-day or day-of-week restrictions placed on an inmate, groups of inmates, or facility-wide. Access Restriction Manager 304 also re-analyses other access restrictions previously checked at step 504 to detect if any restrictions have changed in the time between step 504 and step 512. Such restrictions include disciplinary and other controls configurable by the authority operating the secured facility. In addition to censorship restrictions, Restriction Manager 304 also analyzes content consumption restrictions at this step. For example, a unit of content may have restrictions on the number of plays or otherwise be time or access limited based on content consumption rights for that unit of content. If the Access Restriction Manager 304 authorizes the content to be delivered to the Secured Device at step 512, payment for the content is processed at step 514 by Payment Processor 302. Payment Processor 302 charges, for example, a Debit Account or an Advance Pay Account or periodically bills users for their use and access to content. If payment cannot be processed at step 514, the method ends. If payment is successfully processed, the method continues.

Next, the Connection Manager 306 delivers the content to the requesting Secured

Device at step 516. As described above, the Connection Manager 306 may use any combination of permanent or transient wired or wireless connections to manage the delivery of content to a Secured Device.

At optional step 517, and as further illustrated in FIG. 7, when the system detects that the user/inmate has either paused the content or is no longer streaming the content, the system bookmarks the portion of the video, song, album, clip, etc., so the user can resume the content at the bookmarked portion at a later time.

Finally, at step 518 the Distribution Hub 108 sends usage information to Reporting Services 118. The usage information includes at least information to identify the unit of content and the user who requested the unit of content. Other usage information can be sent to the Reporting Services 118 at this time as well according to the needs of any particular Cloud Service provider.

Method 600 of an exemplary Controlled Environment Secure Media Streaming System including Digital Video Recording is illustrated in FIG. 6. First, as described above with respect to FIG. 5, Distribution Hub 108 receives a request that indicates the unit of content requested on the Secured Device, makes a preliminary check of access restrictions by using Access Restriction Manager 304, and requests the content from the Data Warehouse 106. If the Data Warehouse 106 does not have the requested content, as described at step 508 in FIG. 5, the Distribution Hub 108 makes a request to the Integration Hub 104 to acquire the content from an appropriate Cloud Service.

At step 620 in FIG. 6, the system determines whether the content is available at an appropriate Cloud Service. If the content is available, Integration Hub 104 acquires the content as described in FIG. 5.

When the content is not available at an appropriate Cloud Service, at step 622 Integration Hub 104 determines whether the requested content will be available at a future time.

At step 626, after it is determined that the content will be available at a future time, the system determines when/how the content will be available. In an embodiment, the system determines the date and time that the content will be publicly available from an appropriate Cloud Service. In an alternative embodiment, the system determines the date and time that the content will be broadcast over a medium available to the public, including a television channel.

At step 628, the system schedules a future retrieval of the content based on the determined date, time, and appropriate Cloud Service for the content. In an embodiment, the system schedules a future digital video recording of the content based on the determined date, time, and broadcast medium of the content.

At step 624, the system notifies the user/inmate that the content will not be available in the future. In an embodiment, the system notifies that user/inmate that a future retrieval and/or digital video recording of the content has been scheduled. When the content is retrieved/recorded it is stored in the Data Warehouse 106. The content is then distributed in using the techniques described above in FIG. 5.

Method 700 of an exemplary Controlled Environment Secure Media Streaming System including Digital Video Recording is illustrated in FIG. 7. First, as described above with respect to FIG. 5, Distribution Hub 108 delivers the content to the requesting Secured Device at step 516 using any combination of permanent or transient wired or wireless connections to manage the delivery of content to a Secured Device.

At step 730, illustrated in FIG. 7, the system determines whether the content has been stopped or paused by the user before the content is complete. In an embodiment, the system makes this determination based on whether the Distribution Hub has received a “pause” or “stop” signal from a Secured Device.

When the user pauses or stops the content, at step 734 the system creates or updates a bookmark indicating the last portion of a video, song, etc. the user viewed/heard before pausing the content. The bookmark may be used so when the user resumes the content, the content resumes at substantially the same portion of the video, song, album, clip, etc.

At step 732, the system determines whether the user is still viewing or listening to the content. In an embodiment, Distribution Hub 108 further includes a presence management system that communicates with the Secured Devices. In an embodiment, the presence management system sends a control signal to the Secured Devices, causing the Secured Device to present a graphical user interface (GUI) button requesting the user to indicate whether he or she is still viewing the content.

At step 732 a, the system determines whether the user is interacting with the Secured Device. For example, upon presenting a GUI button requesting the user to indicate whether he or she is still viewing the content, if after a predetermined period of time the user has not responded, the system stops the content and advances to step 734 where the system creates or updates a bookmark.

At step 732 b, the system determines whether a Secured Device is still connected to the Distribution Hub. In an embodiment, the system may send a polling signal to a Secured Device to determine whether the Secured Device is still connected to the Distribution Hub. In an embodiment the polling signal is sent at a regular interval. After sending a polling signal, the system waits a predetermined period of time for a response from the Secured Device. When a response is not received, the system stops the content and advances to step 734 where the system creates or updates a bookmark.

Finally, after creating or updating the bookmark, the Distribution Hub 108 sends usage information to Reporting Services 118. The usage information includes at least information to identify the unit of content and the user who requested the unit of content. Other usage information can be sent to the Reporting Services 118 at this time as well according to the needs of any particular Cloud Service provider.
